On Black Friday I got a great deal on the 2" conversion kit through AG for $22.46. Here's the catch - I did not own the GG3 at that time. I had borrowed one from a friend before, tried it, and thought it was okay. Definitely could use more power, worked pretty good with a thinner microfiber pad. (Of course over the last several years thin foam pads have also come out that help with the power issue ) I had a 7424xp already that I could run 3" pads on so I waited the last few years for a new and better small polisher to come out.
Of course Rupes and Flex have brought out dedicated polishers, but not for pads under 3". I would love to have a Nano but I am not willing to spend the money on one at this time. Thought about the PE 8 but looks kinda big and wanted an orbital. My biggest reasons for wanting a polisher to handle a pad smaller than 3" is for interior polishing such as the black plastic on the center console of our Ford Edge and the piano black b pillars.
Now, back to my purchase of the 2" kit. I figured I would try it on my buddy's polisher. If I liked the result I would buy a GG3 and if not I could easily sell or trade the kit. I tried the kit out last month and was happy with the results. It runs smooth with the 2" pads and I did not have any issue keeping the pads flat to the surface. I tried different speeds between 3 and 6 and it was smooth regardless. It's like the polisher and the kit were made for each other! Well, actually they are, so nice job Griot's! The power is noticeably increased with the smaller pad. I had to be careful not to lose rotation while polishing the deeply curved part of the center console trim where it transitions to the climate control portion of the dash but that is to be expected of any free-spinning polisher. I polished part of a b pillar and it worked very well on that also. It fits my needs for a smaller footprint.
I bought a gift certificate when they were on sale and purchased the 3" Boss HD kit on New Years Eve and I am waiting for my order to be shipped. With using the gift certificate I will have just under $130 into the whole kit (HD polisher, 6 3" pads, trunk bag, towels, and 2" conversion kit). I will add more thin 2" pads at a later date. I have 2" Euro Fiber pads that I am anxious to try on it also.
I can't say how they would work on a rotary. I would think that a thicker pad such as the 2" Flex pads would work better on those. I have the PE 14 with a 2' backing plate and Flex pads but for me it would be too unwieldy for some of the polishing that I want to do, especially in the interior.
